The Irish festivals are never as good as the English ones. Not a dig at Ireland but the best horses come over here for Cheltenham and Aintree over jumps and Newmarket and Epsom for the classics.
You will very rarely see a 2000 Guineas winner go to Ireland or a Derby winner go for the Irish equavilent.
I know Punchestown has managed to attrac the likes of Quevega, Sizing Europe and Voler La Vedette but its lacking Big Bucks, Sprinter Sacre, Finnians Rainbow, Long Run, Kauto Star, Rock On Ruby and more. I understand that they are all unlikely to run at 3 consecutive festivals but if the pull was there then they would.
Like I said it isnt a dig at Ireland, I think it gets bigged up too much and doesnt live up to the hype, and this includes Guineas and Derby day.
